TO ALL WHOM IT MAYONOERN:

Be it known that I, WILLIAM S. OOPER, of the city of Philadelphia, in the count-y of Philadelphia, in the State of' Pennsylvania, have invented a new and useful Improvement in Valves for Water-Closets; and I do hereby declare that the following is a full and exact description thereol, reference being had to the accompanying drawings, making a part of this specification, in which y Figure 1 is an elevation view, half sectional, so as tto show theinside arrangement of myvvalve.

Figure 2 is a sectional elevation ofthe valve and its stem and diverse details on the same.

Figure 3 shows an elevation view of the'stop-cock 'for thechambcr C M.

Figure 4 is a top view of the'sarne.

Figure 5, a bottom view of the same.

The nature of my invention consists in providing water-closets with a valve of a peculiar construction, and which will allow. the water to dow into the basin` freely when the valve is open, said valve closing slowly, and onlyby degrees, so that the water be allowed te pass and ilow a `certain length oi' timcfafter the pressure on the stem ofthe valve has ceased. i p

To enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation. v e

A is the body of the valve. 1), the stem of said valve. L', aleather or India-rubber packing or washer, restingon the seat of the valve when closed, and held in proper place by nut n'. On' top oi" valve D' is set a piece, L, of leather or India-rubber packing, as shown in gs. 1 and 2, its lower 'edge E Gbeing thinned, for the purpose hereinafter shown. .Saidpacking L' is held in proper place by nut N, and its diameter is that of the inside ofthe body A ofthe valve. The valve itself is of' a smaller diameter, so-that between the outside of said valve D' and the inside of L there is an annular space, as shown in tig. 2. On the centre ofthe top of the head Y of valve D' is cut a circular recess of'about one-quarterlof an inch diameter and depth, bearing on its inside face afernale thread, into which is screwed piece B. The bottom of said recess is cut conical, as shown in iig. 2, and between the lower end of the said female thread and the base of conical recess C O there is a small annular recess, A R. The conical bottom C O communicates by means of hole R' with hole R, bored (R' and R) at right angles into centre and side of D', as shown in iig. 2. Piece B is made hollow in R", and R" communicates with annular space R by means of two, three, or more holes, 7i 7i r, figs. 2, 3, 4, and 5. The lower end ofB is made conical, to fit in conical recess C. O.

Valve D' being prepared as aforesaid, is inserted into body (iig. 1,) and I place spring S P on top of D',

`and so that piece B runs up through it. Said spring being pressed down by cap C, screwed on head of A,

will keep the valve close against its scat. E being the vinduction-pipe, and Gthe discharge one, my valve being set/in pro-per position into a water-closet, can be used Veither as a hopper-cork or attached to a pan-closet. The whole `pressure ot the water coming up through induction-pipe E, bears constantly all around head D' and inside leather L, illie vedges E G of' which leather packing L are thereby spread and pressed against the inside face of A, so that L becomes a water-tight packing, allowing no water to pass up between itselt and A. There is a space, whichIA will call chamber C M, between the cap C and the top (iig. 1) of leather packing L. The water under Lfreaches, by its own pressure, the said chamber C M through holes It R', 7L 7:. z, and PW; and as if piece B were screwed tight on to D', there would be no communication between chamber C M and the water under L, the more or less quantity oi' water admitted as aforesaid in chamber C M can be regulated by screwing B on D' more or less tight. New, when I press on stein D and open valve D', the water in chamber C M will be somewhat compressed, its said compression will overbalance the pressure under L, the edge E Gr of L will therefore cease to be compressed against sides' of'A, and the water in chamber() M will be able to discharge itselfbetween L and A. It is obvious that the pressure on top of L in chamber C M, will tend to close the valve :as soon as the pressure on ste-ni D will have ceased to act., therefore the greater or lesser quantity of water admitted through holes R R', z. /L 7i, and R" into chamber C M, will rcgulatc'the greater or lesser speed ofthe closing of valve D'. The movement depends, therefore, entirely on piece B,.fwh ich should be screwed on D'morc or less tight, according to the greater or lesser quantity of water one dcsiresto admit into the basin after the pressure on stem D has ceased.

I do not pretend having invented the regulating-chamber, by means of which I obtain the intended effect' of allowing the water to flow for awhile after the pressure on the stem of the valve haslnen withdrawn. Iam

aware that the principle is known and already used. But the construction of my valve dift'ers in many essen-- tial points from any of those now in use and What I do claim as my invention, and desire to secureby Letters Patent of theUnited States, as a, new article of manufa'eture,;is l y v v A \vatereloset-valve, comprising hollow piece B, annular space A R, and lio'les'R and R, and L h, all constructed and operated in the manner and for the purpose above set forth and described.
